How does Nikon D90 SLR camera take close-up photos? I put it on the table to get a small product. How can I take a clear picture?

All the lenses have a closest focal length, and they can't focus if they are too close. There are several ways to shoot close-ups:

1. Add a close-up on the original lens. Generally, there are 1, 2, 3 and 3 kinds, which can be used alone or in combination. If all are added up, the magnification exceeds 1: 1. Buy an invisible ring, otherwise you can't adjust the aperture and focus. After adding the connecting ring, it is difficult to focus, and the depth of field is shallow. Focus carefully. You can also focus by moving the camera.

2.buy a macro lens. This works best, but it costs money. Macro lenses are not cheap.

3. Add a close-up. This has a great influence on the image quality and is not recommended.
